Lethbridge Herald, The (Newspaper) - July 24, 1974, Lethbridge, Alberta 34 THE LETHBRIDGE HERALD July 1974 Ask Andy SEISMOGRAPHS Andy sends a complete 20- volume set of the Merit Students Encyclopedia to Earl VanPelt age of San Fran- cisco. for his ques- tion How does a seismograph record A major earthquake punches a shuddering whack through the maybe 000 times greater than an ear- ly A bomb Its energy travels in shivering vibrations in various directions at differing speeds This creates earth- quake shocks called seismic waves Seismographs sense and record the assorted seismic waves to form a total picture of the earthquake Groups of separated seismographs compare notes to pinpoint the where the upset occurred in the earth s crust Around the or so seismology stations record about 1 000 earthquakes a most of them too slight to be felt bv the average citizen Their major instruments are batteries of seismographs designed to report the assorted shock waves sent zinging through the planet Seismographs come in different styles to cope with the various vibrations of diflerent seismic waves One style is the pendulum seismograph Its pendulum is a heavy weight suspended to stay still while the rest of the equipment shudders Another is the strain seismograph Its two sturdy posts sway together and apart as vibrating waves pass by in the ground below All seismographs are fitted with electric gear to record their sensitive changes on rolls of revolving graph paper or on magnetic tape You might suppose that such an earthquake station runs like clockwork until vou grasp the complexity of seismic waves These vibrating shock waves come in three major types with numerous variations The hrst to arrive are pnmarv or P' waves These roar forth from the traveling through the rigid crust at perhaps 3la miles per second M deeper levels through more elastic they speed up to perhaps miles per second waves cause back-and-forth vibrations in the direction in which they are traveling The next arrivals are secon- dary or waves. These vibrate sideways as they go Their speeds range from two miles per second to 4Vz miles per second through more rigid materials waves cannot shiver through the earth's molten which is somewhat bigger than the planet Mars The last arrivals are the waves that daw- dle through the crustal sur- face Some of their leisurely waves are 500 miles long As a a seismograph specializes in one type of seismic wave Some report vertical and others horizontal displacements in the earth Some record the waves that penetrate the entire the surface L waves and the waves that curve down to the core and up again The speeds and arrival times of the various shock waves give clues to the location and intensity of a ma- jor quake But masses of data must be computed and com- pared to verify the facts Data from three separated stations is compared to pin- point the where the earthquake occurred in the earth s crust Masses of details from many seismographs must be analyz- ed to estimate the strength or intensity of an earthquake This takes time Measuring the changes that a major quake can make in the earth's crust takes even longer Questions asked by chil- dren of Herald readers should be mailed to Ask P.O.

About air it depends again on the cause Clearly if the ventricular tachycardia is caused by serious heart disease one wouldn't travel until after recovery For recurrent attacks without other medical problems one can travel by plane Even if an attack should occur in the plane it would be no worse than on the ground The problem might be in getting immediate medical attention Commercial air planes are not really that much different from a bus The cabin altitude is not allowed to be over feet and usually is much less than that Denver has an altitude of and the mountains nearby are much higher Send your questions to Dr. in care of this P.O. Box Radio City New N.Y. 10019. For a copy of Dr. Lamb's booklet on send 50 cents to the same address and ask for booklet.
